0.37b5 [Nicola Salmoria]


- shangha3: The zoom used for the "100" floating score when you remove tiles is very rough.

- heberpop: Unknown writes to sound ports 40/41

- blocken: Incomplete zoom support, and missing rotation support.


- Custom blitter GA9201 KA01-0249 (120pin IC): This is a tile-based blitter that writes to a frame buffer. The buffer is never cleared, so stuff drawn is left over from frame to frame until it is overwritten.

- Tiles are stored in ROM and have a fixed 16x16 size. The blitter can draw them as single sprites (composed of one or more tiles in the horizontal direction), or as larger sprites whose tile codes are picked from a tilemap in RAM.

- Sprites can be zoomed, distorted and rotated.

- Shadows are supported on pen 14 (shangha3 makes heavy use of them) but it's not clear how they are turned on and off. heberpop definitely doesn't use them, pen 14 is supposed to be solid black (outlines).
